Definitions

  • a catalyst for purifying an exhaust gas is placed in an exhaust passage for this type of system.
  • This catalyst is deteriorated due to harmful components (such as lead and sulfur) in fuel and excessive heating.
  • harmful components such as lead and sulfur
  • an exhaust gas purifying ratio is degraded, and exhaust emission is increased.
  • various devices for determining deterioration of the catalyst are conventionally proposed (such as Japanese Patent Application Publication No. 1993(H5)-133264 and 2004-28029 ).
  • an expansion ratio can also be changed by the change in the mechanical compression ratio.
  • the on-board diagnosis of the intake and exhaust system (on-board diagnosis influenced by a state of the exhaust gas in particular) is properly performed in the engine system provided with the engine in which the compression ratio or the expansion ratio is variable. Therefore, precision of the diagnosis can be improved more than that of the conventional examples.
  • the control device 2 is formed so as to control operation of the engine 1 provided with the above configuration, determine (diagnose) states of the parts of the engine system S, and appropriately display determination (diagnosis) results to a driver.
  • diagnosis states of the parts of the engine system S
  • display determination diagnosis
  • the mechanical compression ratio, the actual compression ratio, and the expansion ratio are controlled based on the operation state of the engine 1 such as a warming-up state and a load state.
  • Step 320 it is determined whether or not the compression ratio control system normally works. Normality determination of this compression ratio control system is performed as follows.
